ALMAL Fire-Rated 1-Hour LDR Sandwich Panel

Insulated sandwich panels with aluminium cladding
U-value for walls and roof: 0.451 W/m²K

Composition

Al: Raw, anodised or pre-painted aluminium cladding, 10/10 mm thick
M: Rock wool core, 80 mm thick, with integrated timber framework
Al: Raw, anodised or pre-painted aluminium cladding, 10/10 thickness

Possible integrations:

• Steel, aluminium, timber, expanded PVC structures, etc.
• Pipe penetrations: steel, aluminium, PVC, IRO
• Localised reinforcements in sheet steel, aluminium or plywood strips

Advantages of integrating the framework

It consists of a solid timber or solid finger-jointed timber structure.
It is directly integrated into the panel to make it monolithic and structural.
This technique offers:
• excellent air and water tightness
• timber protected from the elements and insects
• very good fire resistance and stability
• excellent air and water tightness
• a significant reduction in thermal bridges to prevent condensation
• enhanced insulation with thin walls
• easy integration thanks to a smooth interior surface
• Quick fixing directly into the interior cladding
• Lifting under load is possible thanks to its strength, forming a monocoque structure
• Easier crane handling due to control of the dead weight of the assembled unit

Classifications

• EFECTIS fire performance certificate B-s1,d0
• EFECTIS test report: 1-hour fire resistance on both sides
• EFECTIS laboratory TECHNICAL APPROVAL for 1-hour fire resistance for assemblies and flooring to validate a technical shelter or shelter as a whole
